test: Implement Unit Test for Password Hashing

[benoit-bremaud]

Summary

This issue aims to implement unit tests to verify that user passwords are being hashed correctly before being saved to the database. It is crucial to ensure that plain text passwords are not stored, thereby enhancing the security of user data.

Context

Proper hashing of passwords is a fundamental security practice. It ensures that even if the database is compromised, the actual passwords cannot be easily retrieved. The tests will focus on validating that the hashing function is correctly implemented and that passwords are stored in a hashed format.

Objectives

• Implement unit tests for the password hashing function.
• Ensure that the hashing function does not store passwords in plain text.
• Verify that the hashed passwords match the expected hash format (e.g., bcrypt).

Acceptance Criteria

• The hashing function must not return the plain text password.
• The hashed password must match the expected format (e.g., bcrypt hash format).
• Tests should include validation of both the hash and compare functions to ensure consistency.

Tasks

• Create and initialize a new working branch
  • Use the branch name following the conventions specified in the CONTRIBUTING.md guide.
  • Branch name format: test/issue-number-password-hashing
• Implement unit tests for the password hashing function.
